The arrival of Europeans in the New World had profound and long-lasting results for the native peoples. The record for the impact of this fundamental change in culture, society, and biology of Native Americans is well documented historically. This paper reviews the biological impact of the arrival of Europeans on native populations via the study of pre- and postcontact skeletal remains in Spanish Florida, the region today represented by coastal Georgia and northern Florida. The postcontact skeletal series, mostly drawn from Roman Catholic mission sites, are among the most comprehensive in the Americas, providing a compelling picture of adaptation and stress in this setting. Study of paleopathology, dental and skeletal indicators of physiological stress, stable isotope (carbon and nitrogen) analysis, tooth microwear, and skeletal morphology (cross-sectional geometry) reveals major alterations in quality of life and lifestyle. The bioarchaeological record indicates a general deterioration in health, declining dietary diversity and nutritional quality, and increasing workload in the contact period. The impact of contact in Spanish Florida appears to have been more dramatic in comparison with other regions, which likely reflects the different nature of contact relations in this setting versus other areas (e.g., New England, New France). The bioarchaeological record represents an important information source for understanding the dynamics of biocultural change resulting from colonization and conquest. 相似文献

Narendra Modi's election as India's prime minister in May 2014 has generated speculation that a new ‘Modi doctrine’ is emerging in Indian foreign policy. This article assesses the evidence for that claim. It argues that a ‘doctrine’ should embody a set of clearly stated principles for foreign policy making. It analyses the main achievements of Modi's policy in the months after his election. It finds that while Modi has brought new energy to the conduct of foreign policy, his approach is essentially pragmatic, and his objectives are similar to those pursued by his two immediate predecessors—Atal Bihari Vajpayee and Manmohan Singh. 相似文献

The mapping abilities of four-year-old children in York, England, Durban, South Africa, Tehran, Iran, Mexico City, Mexico and Evanston, Illinois, USA were investigated, using a methodology involving air-photo identification and simulated navigation on an air photo. The results show that essential mapping abilities (perspective and scale transformations) are well developed by the age of four in these cultures, and provide some evidence in support of the hypothesis that mapping abilities emerge without training in very young children of all cultures. 相似文献

This paper presents an overview of the Late White rock paintings of south-central and southern Africa. It is argued that the most recent paintings were produced by matrilineal or bilateral Bantu-speaking agriculturists, although links with earlier hunter-gatherer groups are also implied. It is noted that certain motifs reoccur over great geographical distances. Ethnographic data are used in order to suggest a possible meaning for these motifs and for the paintings in general. It is argued that many of these paintings embody conceptual associations linking them to fertility. A general outline of the most obvious associations is presented, and a plea is made for detailed regional surveys in order to explain temporal and spatial differences.
Résumé Cet article présente une vue d'ensemble sur les peintures rupestres Late White d'Afrique australe et du sud de l'Afrique centrale. Il défend l'idée que les peintures les plus récentes ont été produites par des agriculteurs matrilinéaires ou bilatéraux parlant le bantou, tout en supposant des rapports avec des groupes plus anciens vivant de la chasse et de la cueillette. On remarque que certains motifs réapparaissent à de grandes distances géographiques. L'article s'appuie sur des données ethnographiques pour suggérer une signification possible à ces motifs ainsi qu'aux peintures en général. Il démontre que nombreuses de ces peintures représentent des associations conceptuelles les associant à la fertilité. Un aperçu général des associations les plus évidentes est présenté et les auteurs demandent que des études régionales détaillées soient effectuées afin d'expliquer les différences temporelles et spatiales.相似文献
